I sent you logs to GPT4 for analysis and this is the summary.
In the logs provided from an IPFire user, the DHCP client daemon (dhcpcd) successfully starts and goes through the process of connecting to a wireless access point, soliciting, and then obtaining a DHCP lease for the red0 interface. This lease acquisition completes without issue, with the daemon configuring the necessary network routes and setting up a default gateway based on the leased IP address. However, approximately a minute after the successful lease negotiation, an unexpected behavior occurs: dhcpcd initiates the process of releasing the leased IP address and removing the associated network routes. This action appears to be untriggered by any user command or manual intervention, suggesting an abnormal behavior within the DHCP client’s operation.
Following this unexpected lease release initiation, the daemon encounters problems with process management, specifically highlighted by its attempts to send a SIGALRM signal to a process that fails to exit as expected. The daemon makes multiple attempts to terminate this process, but each attempt fails, leading to repeated warnings in the log. This issue culminates in an error message indicating that dhcpcd cannot find or access a necessary file or directory, followed by the daemon’s exit. The close temporal link between the unexpected initiation of the lease release and the process management difficulties suggests these events may be related, indicating a singular underlying issue affecting dhcpcd’s operation. This situation points to a complex problem within the DHCP client mechanism, potentially involving software glitches, configuration errors, or unexpected system or network events that disrupt the normal DHCP client operation.
If your internet connection is on coax cable, check for faulty cable splitter.
I fixed a friend similar problem, found faulty splitter with a broken solder as the root cause.
